java.lang.Object

org.openimaj.image.objectdetection.FilteringObjectDetector<IMAGE,DETECTED_OBJECT,FILTERED_OBJECT>

Type Parameters:

IMAGE - Type of image in which the detection happens

DETECTED_OBJECT - The type of object emitted by the inner detector

FILTERED_OBJECT - The type of object emitted by the filter

All Implemented Interfaces:

ObjectDetector<IMAGE,FILTERED_OBJECT>

public class FilteringObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,DETECTED_OBJECT,FILTERED_OBJECT>
extends Object
implements ObjectDetector<IMAGE,FILTERED_OBJECT>

Constructor Detail

FilteringObjectDetector

public FilteringObjectDetector(ObjectDetector<IMAGE,DETECTED_OBJECT> detector,
                               DetectionFilter<DETECTED_OBJECT,FILTERED_OBJECT> filter)

Construct with the given detector and filter.

Parameters:

detector - the detector

filter - the filter

Method Detail

detect

public List<FILTERED_OBJECT> detect(IMAGE image)

Description copied from interface: ObjectDetector

Detect objects in the given image and return representations of them. Representations often cover things like the spatial location in the image of the detected object, however, this is implementation defined.

If no objects are detected, null or an empty list may be returned.

Specified by:

detect in interface ObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,FILTERED_OBJECT>

Parameters:

image - the image to detect the object in.

Returns:

a list of detections or null if none are found.

setROI

public void setROI(org.openimaj.math.geometry.shape.Rectangle roi)

Description copied from interface: ObjectDetector

(Optional operation).

Set the region of interest within the image to search for objects. Setting to null means to search the whole image.

Specified by:

setROI in interface ObjectDetector<IMAGE extends org.openimaj.image.Image<?,IMAGE>,FILTERED_OBJECT>

Parameters:

roi - the region of interest
